If you ask many people why gamble, their response is "it is like a drug" (5). Compulsive gambling is a behavior which may rely on brain circuits that evolved to help animals assess rewards important to their survival. Researchers have found that those same circuits are used by the human brain to assess social rewards. They found that the brain systems that detect and evaluate such rewards generally operate outside of conscious awareness. The study said that much of what happens in the brain goes outside of conscious awareness. There are automatic brain circuits which affect activities such as gambling (2). However, this challenges prior notions which say that people make conscious choices about their everyday decision making. If people can get themselves to work unconsciously, how does the brain really know what it must pay conscious attention to? Also, how did evolution create a brain which makes such distinctions?
